May be disabled by setting:
self.whitespace_keepalive = False
The keepalive interval can be adjusted using:
self.whitespace_keepalive_interval = 300
The default interval is 5min.
If wait=True, then the disconnect call will block until
the send queue has emptied.
WARNING: Using wait=True when more stanzas are being added to the
queue than can be processed such that the queue is never empty
will cause the disconnect call to block indefinitely without actually
disconnecting.
The error bubbles through the event processing loop, breaking it and
hanging the application.
Instead, there is now a .exception(e) method on XMLStream which may
be overridden or reassigned that will receive all unhandled exceptions
(read: not XMPPError) from event and stream handlers.
If a stanza handler raised an exception, the exception was processed
and replied by the modified stanza, not a stanza with the original
content.
A copy is now made before handler processing, and if an exception occurs
it is the copy that processes the exception using the original content.
For now, session_end is the same as disconnected, but once support is
added later for stream management, the two events will become distinct.
Plugins should add handlers for session_end for cleaning any session
state.
Backoff was only being done for the initial connection attempt
before. Now any reconnection will start with a minimum 1 sec
delay which will approximately double between attempts.
JIDs with Unicode values were being encoded by the JID class
instead of leaving them as just Unicode strings.
It may still be a good idea to use
from __future__ import unicode_literals
pretty much everywhere though.
Fixes issue #88.
Each interface, say foo, may be overridden in three ways:
set_foo
get_foo
del_foo
To declare an override in a plugin, add the class field
overrides as so:
overrides = ['set_foo', 'del_foo']
Each override must have a matching set_foo(), etc method
for implementing the new behaviour.
To enable the overrides for a particular parent stanza,
pass the option overrides=True to register_stanza_plugin.
register_stanza_plugin(Stanza, Plugin, overrides=True)
Example code:
class Test(ElementBase):
name = 'test'
namespace = 'testing'
interfaces = set(('foo', 'bar'))
sub_interfaces = set(('bar',))
class TestOverride(ElementBase):
name = 'test-override'
namespace = 'testing'
plugin_attrib = 'override'
interfaces = set(('foo',))
overrides = ['set_foo']
def setup(self, xml):
# Don't include an XML element in the parent stanza
# since we're adding just an attribute.
# If adding a regular subelement, no need to do this.
self.xml = ET.Element('')
def set_foo(self, value):
print("overrides!")
self.parent()._set_attr('foo', 'override-%s' % value)
register_stanza_plugin(Test, TestOverride, overrides=True)
Example usage:
>>> t = TestStanza()
>>> t['foo'] = 'bar'
>>> t['foo']
'override-bar'
